Metal-Oxide Varistors (MOVs) Surface Mount Varistors > CH Series CH Varistor Series RoHS Description CH Series transient surge suppressors are small, metal-oxide varistors (MOVs) manufactured in leadless chip form. They are intended for use in a variety of applications from low voltage DC to off-line board-level protection. These devices, which have significantly lower profiles than traditional radial lead varistors, permit designers to reduce the size and weight and increase the reliability of their equipment designs. CH Series varistors are available in a voltage range from 14V to 275V (V ), and energy ratings up to 8J. M(AC)RMS See the Littelfuse Multilayer Suppressor Series also. Agency Approvals Recognized under the components program of Features Underwriters Laboratories. • RoHS compliant • Supplied in tape and Agency Agency Approval Agency File Number reel or bulk pack • Leadless, surface mount chip in 5 • No derating up to UL1449 E320116 x 8mm Size 125ºC ambient • Voltage ratings • High surge rated V 14V to 275V up to 600A M(AC)RMS Absolute Maximum Ratings • For ratings of individual members of a series, see Device Ratings and Specifications chart Continuous CH Series Units Steady State Applied Voltage: AC Voltage Range (V ) 14 to 275 V M(AC)RMS DC Voltage Range (V ) 18 to 369 V M(DC) Transient: Peak Pulse Current (I ) TM For 8/20µs Current (See Figure 2) 100 to 600 A Single Pulse Energy Range For 10/1000µs Current Wave (W ) 1.0 to 8.0 J TM Operating Ambient Temperature Range (T) -55 to +125 ºC A Storage Temperature Range (T ) -55 to +150 ºC STG Temperature Coefficient (αV) of Clamping Voltage (V) at Specified Test Current <0.01 %/ºC C CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device.

Current, Energy and Power Derating Curve Continuous power dissipation capability is not an applicable design requirement for a suppressor, unless transients 100 occur in rapid succession. Under this condition, the E 90 average power dissipation required is simply the energy U AL 80 (watt-seconds) per pulse times the number of pulses V D 70 per second. The power so developed must be within ATE 60 the specifications shown on the Device Ratings and F R 50 O Specifications Table for the specific device. Furthermore, NT 40 the operating values need to be derated at high tempera CE 30 R tures as shown in this diagram. Because varistors can only PE 20 dissipate a relatively small amount of average power they 10 are, therefore, not suitable for repetitive applications that 0 -55 50 60 70 80 90 100 110 120 130 140 150 involve substantial amounts of average power dissipation.
